Description

Tire assembly

Technical Field

The invention relates to the field of automobiles, in particular to a tire assembly.

Background

The tires support the entire vehicle and provide the necessary power for travel. With the improvement of the automobile technology, the road surface condition is improved, and the running speed of the automobile is gradually increased. Meanwhile, with the popularization of electric vehicles at present, tires with high aspect ratio are favored by users. Safety and comfort of the vehicle at this time become more of a concern to the passengers, especially for tires with a high aspect ratio.

The condition of the road surface is particularly important when the automobile is on an expressway. When the road surface has sundries such as brick obstacles, the huge impact of the tire is likely to damage the tire, cause the tire to be damaged, bulge and even burst, and also cause the impact of the steel wheel in some cases, which affects the safety of passengers. Meanwhile, the noise of the tire is an important noise source when the automobile runs, and particularly, the noise of the tire is obvious when an engine is omitted in a future electric vehicle.

Therefore, it is necessary to sufficiently study the existing problems or disadvantages including the above-mentioned cases so as to improve them.

Detailed Description

It is easily understood that according to the technical solution of the present invention, a person skilled in the art can propose various alternative structures and implementation ways without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

In the following description, various parameters and components are described for different configurations of embodiments, and these specific parameters and components are only by way of example and do not limit the embodiments of the present application.

An embodiment according to the invention is shown in connection with fig. 1, where it can be seen that: the tire assembly includes a tire 1, a rim 2, and a buffering noise-absorbing frame member 3 mounted at a surface of the rim, the buffering noise-absorbing frame member 3 being located inside a space formed by the tire 1 and the rim 2, the buffering noise-absorbing frame member 3 including a buffer 31 and a noise-absorbing member 32. The tire component has a simple structure, can absorb and mitigate the energy of large instantaneous impact force, can absorb the noise from tire contact and a tire inner cavity, and improves the impact resistance, NVH performance and tire silencing capability of the tire.

The noise-absorbing frame member 3 is adhered to the rim 2 by glue. Alternatively, the frame member 3 is fixed to the rim 2 by bolts or the like.

The cushion 31 is arranged higher than the rim edge 21 in the radial direction of the tire to ensure that a large impact is not transmitted to the rim edge 21 when the tire passes over an obstacle road surface, causing an adverse safety hazard.

As shown in fig. 2, when the tire 1 hits a bump road surface 4, it is known that the higher the speed and the larger the bump, the larger the deformation amount of the tire according to the energy at the time of impact, and when the speed reaches a certain speed, the bump road surface 4 hits the rim edge 21, causing an adverse damage and a safety hazard. In the present application, the cushion member 31 can cushion the instant impact force of the tire, and reduce the probability that the ground will collide with the rim edge 21.

The buffer member 31 is a buffer member having a certain rigidity but capable of supporting a certain load. Energy for moderating a large instantaneous impact force can be absorbed. But also to avoid the ground hitting the rim edge 21. The material of the buffer member 31 can be rubber, plastic and the like.

The height of the cushion member 31 can be adjusted according to the actual aspect ratio of the tire, and the height of the cushion member 31 can be set higher for a tire with a high aspect ratio. Of course, the height of the buffer 31 can also be adjusted in a targeted manner according to actual requirements.

The noise absorbing pieces are filled between the buffer pieces, and the purpose of absorbing noise is achieved. And air holes are formed in the noise absorbing piece. The noise absorbing piece is made of one or more of plastic, fiber and foam.

Fig. 3 shows a cross section of the tire assembly of fig. 1 in a plane perpendicular to the tire radial direction, wherein, as viewed in the plane shown in fig. 3, i.e., a plane perpendicular to the tire radial direction, the cushion members 31 extend perpendicular to the rotational axis of the tire, and the noise absorbing members 32 are filled between the cushion members 31. At this point, the 31-damper may extend continuously about the axis of rotation of the tire, forming a ring around the rim.

Another embodiment according to the invention is shown in fig. 4, in which the cushion element 31 extends at an acute angle (or at an obtuse angle) to the axis of rotation of the tire, seen in the plane shown in fig. 4, i.e. perpendicular to the radial direction of the tire. The noise absorbing members are filled between the cushioning members such that, as viewed in the direction of the rotational axis of the tire, the left and right sides (or one of the left and right sides) of the noise absorbing member 32 in fig. 4 are exposed in the space formed by the tire and the rim. In this way, by mounting the cushion member 31 and the noise absorbing member 32 on the rim 2 at an angle, advantages can be achieved in that: when the tire is subjected to impact, the contact surface of the buffer member 31 and the tire is more uniform; in addition, because the two sides of the noise absorbing piece 32 are open, the noise absorbing area can be increased, and the noise absorbing effect is enhanced.

To sum up, the application provides a tire subassembly with buffering protection and noise absorption, and its simple structure easily realizes, can promote tire impact and NVH performance. The energy of large instantaneous impact force can be absorbed and alleviated, and the ground can be prevented from colliding with the edge of the rim; meanwhile, the noise can be absorbed, and the silencing capability of the tire is improved.

The technical scope of the present invention is not limited to the above description, and those skilled in the art can make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and such changes and modifications should fall within the protective scope of the present invention.
